SAWIN'G OUTFIT.

Application filed April as, 1925-. Serial No. 26,426.

This invention relates to certain improvements in sawing outfits and itis an object of the invention to provide a device of this generalcharacter adapted to have the saw driven by the engine of a motor drivenvehicle, such as a tractor.

Another object of the invention is to provide a device of this kindwhich, when in working position with respect to the motor driven vehiclefor a sawing operation, has a portion thereof supported directly uponthe axle of the vehicle whereby undue vibration of the radiator or otherparts of the body of the vehicle as would otherwise be created by thesawing outfit is avoided.

Another object of the invention is to provide a device of this kindconstructed in a manner to permit the same to be readily hitched to atractor or the like when it is desired to transport the outfit from onelocation to the other and wherein the outfit is so constructed that whenit is in working position for a sawing operation ready access may be hadat all times to the crank for the motor.

It is also an object of theinvention to construct an outfit of thischaracter in a manner whereby an unobstructed driving connection may behad between the saw shaft of the outfit and the pulley of a tractor andwhereby the raising of the front Wheels of the tractor avoids the use ofa belt tightening device. 1

The invention also has for an object to provide a device of this generalcharacter provided with a sliding table movable with respect to the sawto facilitate the desired cutting of the work.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved sawingoutfit whereby certain 11nportant advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more'fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the betterunderstood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein b Figure 1 is a view in side elevation of a r sawingoutfit constructed in accordance with an embodlment of my lnvention, thecoact-- ing tractor being diagrammatically indiizated by broken lineswith'the pulley in full mes;

Figure 2 is an enlarged fragmentary sectional view taken substantiallyon the line 2-2 of Figure 1;,

Figure 3 is a view'in perspective of the. table as herein disclosedunapplied;

Figure 4 is a View in. elevation of my improved device withthe drafttongue appliedthereto;

Figure 5 is a view in top plan of the structure as illustrated in Figure1 with the table removed.

As disclosed in the accompanying drawings, my improved'outfit comprisestwo parallel beams 1 of requisite dimensions having their forward endssubstantially in transverse alignment with the rear portion of one ofthe beams extending a desired rearwardly of the second beam. The rearportions of the beams 1 are connected by the transversely disposedmembers 2, while the forward extremities of said beams 1 are connectedby the transversely disposed member 3, said members 2 and 3 serving tomaintain the beams 1 in desired spaced relation.

Suitably secured to and underlying the rear portions of the beams 1 is atransverse ly disposed axle 4 the extremities of which extending adesired distance beyond the beams 1 and having mounted thereon thesupporting wheels 5; Underlying the forward end portions of the beams 1and secured thereto are the plates 6 the outer end portions of whichbeing provided with the sleeves or barrels 7 whereby the forward endportions of the beams 1 may be coupled by the pins 8 or the like to thehitch members 9 clamped or otherwise secured to the front axle A ofthetractor T or kindred motor driven vehicle, said tractor being preferablyend portion of said tongue X being adapted to be coupled in a well knownmanner with the conventional hitch of the tractor so that when desiredthe outfit may be readily trans ported from one locality to another.This tongue X may be readily and conveniently removed and applied as theoccasions of practice may require.

Each of the beams 1 at the rear portion thereof is provided with theupstanding longitudinally spaced posts 1%, the upper portions of whichbeing connected by a horizontally disposed beam 15. The forward post 1%carried by one of the beams 1 is disposed on an outward incline toassure no hindrance or obstruction being offered to the drive belt Dcoacting with the pulley P and the pulley 16 fixed to the saw shaft 17.I

T he saw shaft 17 is rotatably supported by the upstanding bearings 18carried by the horizontally disposed beams and extends outwardly beyondone of such beams, said extended .portion of the shaft having fixedthereto in a well known manner a circular saw S. The beam adjacent tothe saw S, as herein disclosed, extends a desired distance rearwardly ofthe beam 1 therebelow. Suitably secured to the upper surface of thishorizontally disposed beam 15 rearwardly of the shaft 17 is a wear plate19 and ext-ending transversely of the beam 15 immediately adjacent tothe rear end of the plate 19 is the stop plate 20 projecting beyondopposite sides ofsaid beam. Rotatably supported by the side faces ofthis beam 15 and extending laterally therefrom are the rollers 21 whichare engaged by the flanges a of the elongat ed members a 22 U-shap'ed incross section the rear end portions of each of said memy bers beingconnected by the transversely disposed member 23 to provide meanswhereby the members 22 will have unitary endwise movement in eitherdirection.

At a predetermined point inwardly of the member 23 and also rearwardlyof the saw S when the members 22 are at the limit of their rearwardmovement is an upstanding bracket 24 in the form of an inverted U and ofa height to readily pass over the saw S as the members 22 are advanced.The forward end portion of the outer member 22 has secured thereto anupstanding bracket 25 also substantially U-shaped in form with its innerside member 25 terminating above the adjacent beam 15 and above theplane occupied by'the shaft 17. The forward end portion of the innermember 22 has pivotally engaged therewith a short arm 26 adapted to bebolted or otherwise dctachably connected with the free end portion ofthe shorter arm 25. V/ith the arm 26 detached from the arm 25 and swungdownwardly the b acket-25 may readily pass over the shaft 17,particularly in assembling the device. Connect ed to the arm 26 and tothe cross member 2? connecting the beams 15 is a retractile memher orspring 28 which operates to constantly urge rearwardly the membersMounted upon and sultably secured to the upstandmg brackets 24 and 25 1sa guard G, said guard including an outer side plate extending over andterminating below the outer face of the saw S and with an inner sideplate terminating above the shaft 17.

The rear portion of the inner member 22 has secured thereto anoutstanding and laterally disposed arm 29 braced or reinforced by thearm 30 interposed between and secured to the outer end portion of thearm 29 and to the inner member 22 at a desired point in advance of thearm 29. The arm 29 at its outer end portion is provided with anenlargement or cushion 31 against which the body of the aperture isadapted to press to force the members 22 in a direction toward the saw Sso that the work positioned upon the plate 19 will be moved by the crossmember 23 into proper engagement with the saw S.

It is to be noted that with my improved outfit the front axle of atractor provides supporting means therefor whereby the radiator or otherparts of the vehicle are not subjected to any undue vibration and itwill be further readily understood that no tightening device need beemployed in connection with the belt D as the belt may be readilymaintained taut by raising the front wheels of the tractor which may bereadily done by a board or the like. Furthermore it is to be noted thatthe connection of the beams 1 with the front axle of the tractor is suchto permit ready access to the usual crank for starting the motor of thetractor.

From the foregoing description it is thought to be obvious that a sawingoutfit constructed in accordance with my invention is particularly welladapted for so by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.
